Description
technical field [0001] The invention relates to the field of modeling and simulation, in particular to a simulation method and device for a metering circuit of an electric energy meter. Background technique [0002] The smart energy meter is an important device for establishing a nationwide smart grid, and the accuracy of its energy measurement is directly related to the vital interests of users and the State Grid. The metering circuit of the smart energy meter can be divided into two parts: an analog circuit and a digital circuit. At present, the simulation analysis of the electric energy meter is only for one part, and the actual measurement chip internal A / D conversion circuit working principle of the electric energy meter and the digital calculation method of parameters such as active power are rarely considered in the simulation. This will make the simulation results of the metering circuit of the electric energy meter unable to accurately reflect the actual metering s...
